Volume 8, Book 74, Number 249:
Narrated ‘Abdullah:
When we prayed with the Prophet we used to say: As-Salam be on Allah from His worshipers, As-
Salam be on Gabriel, As-Salam be on Michael, As-Salam be on so-and-so. When the Prophet fin –
ished his prayer, he faced us and said, “Allah Himself is As-Salam (Peace), so when one sits in the
prayer, one should say, ‘At-Tahiyatu-lillahi Was-Salawatu, Wat-Taiyibatu, As-Salamu ‘Alaika aiy –
uhan-Nabiyyu wa Rah-matul-lahi wa Barakatuhu, As-Salamu ‘Alaina wa ‘ala ‘Ibadillahi assalihin,
for if he says so, then it will be for all the pious slave of Allah in the Heavens and the Earth. (Then he
should say), ‘Ash-hadu an la ilaha illalllahu wa ash-hadu anna Muhammadan ‘Abduhu wa rasulu-
hu,’ and then he can choose whatever speech (i.e. invocation) he wishes ” (See Hadith No. 797, Vol. 1)
